SAFETY-LAM P FOR BEER-VATS.

SFECIFIGATION forming part of Letters Patent No. 504,702, datedSeptember 12, 1893.

Application filed February 20, 1898. Serial No, 462,950. (No model.)

To aZZ whom it may concern.-

Be it known that we, MICHAEL BORLING- HAUSEN and PETER BORLINGHAUSEN,citizens of the United States, residing at Cleveland, in

the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improve nents in Safety-Lamps forBeer-Vats, of whlch the following is a full, clear, and exactdescription.

Our invention consists of a parabolical reflector having a flaring mouthand openings to receive the upper part of a lamp and the lower portionof the lamp-chimney, said reflector and lamp being attached to a rodfixed in a pedestal or base and capable of adjustment upon said rod.

The object of our improvement is to provlde a device for lighting theinterior of a beer vat, or similar vessel, without introducing the flametherein. The walls of a vat, upon the inside, become coated withalbuminous and other deposits, from the beer, which must be removedperiodically and a fresh coat of shellac applied to said walls. .Vithour apparatus the rays from the lamp are reflected over the interior ofthe vat, providing all the light necessary for the operator inside, andthere is no danger of an explosion from the rapid evaporation of thealcohol contained in the shel- 0 lac, since the flame is removed aconsiderable distance from the vat itself.

That our invention may be seen and fully understood by others, referencewill be had to the following specification and annexed 3 5 drawlngs,forming a part thereof, in which Figure l is a sectional view of ourinvention, showing its application, and Fig. 2, a top view of thedevice.

Similar letters of reference designate like 0 parts in the drawings andspecification.

The base A has the casters A, Fig. 1, attached to the bottom thereof andthe rod B arising from the center. The brackets C and D are providedwith the integral sleeves C ,5 and D respectively and the set-screws E,E,

by means of which said brackets are adjusted to the rod B, at anydesired height, or may be allowed to swing completely around said rod.The bracket 0 supports the lamp F and the bracket D encircles said lamp,holding the same securely in place. The lamp F may be of the ordinaryconstruction, but should furnish a brilliant light, and is provided withthe chimney F. The reflector G is parabolical in longitudinal sectionand consists of the two metallic sections H and H, said sections beingdetachable, one from the other. The section H is secured to the sleeve 1by a screw and nut, or in any other suitable manner, and is providedwith the opening J at the top and the opening J, Fig. 1, at the bottom.The part of the lamp E which contains the burner is inserted through theopening J and the lower portion of the chimney F projects through theopening J, as will be seen by referring to Fig. 1. The sleeve I issituated above the sleeve D and has the set-screw E, by means of whichsaid sleeve and the reflector G are secured to the rod B at anyelevation desired, or may be allowed to swing around. The rear end ofthe section H is closed and the front terminal is open, with the collarH encircling the outside leaving the shoulder H upon the inside. Thesprings K, two or more in number, are attached to the exterior of thecollar H and project beyond the front end of the section H. The sectionH, of the reflector G is formed substantially as shown in the drawings,having the front end or mouth curved to an angle of about sixty degreesand flaring. The small end of the section H forms a tight joint with theshoulder H of the section H, and is held in place by the springs K. Theentire interior of the reflector G is electroplated in order to stronglyreflect the rays of light, from the lamp F, into the vat. The section Hmay be rotated so as to throw the light into any and every part of thevessel which is being illuminated.

In Fig. 1, the vat L is shown, partially broken away to expose theflaring mouth of the reflector G, and the dotted lines Z, Fig. 2, denotethe relative position of the vat to the reflector. The front end of thereflector G is inserted, through the man hole L, Fig. 1, within the vatL and reflects the light over a large area, as indicated by the linesI), Fig. 1.

Our reflector may be used for illuminating any vessel, tank, orreceptacle into which it is undesirable to carry a lighted lamp.

In place of the'brackets O and D any suit- 5 able support for the lamp Fmay be provided.

What We claim as our invention, and desire to secure by Letters Patent,is

1. Alamp for beer vats, in combination with parabolical reflectorconsisting of two sec to tions, the rear section having an external col-I 5 month, in the manner substantially as and for the purpose set forth.

2. In a safety lamp for beer vats, a rod fixed to a base, the brackets Oand D adjustably attached to said rod by integral sleeves andset-screws, and a lamp, in combination with the parabolical reflector Gsecured to the sleeve I, said sleeve I being adjustably attached to saidrod, above said bracket, by a set-screw, in the manner substantially asand for the purpose set forth.

In testimony whereof we afiix our signatures in presence of twowitnesses.
